How Does Bluetooth Work and how it helps you Stay Connected?

Articles

There are so many ways to connect devices that it may seem like it is all the same but with different names. However, the technology behind all wireless connection methods is different. Wi-Fi, Bluetooth, LTE and infrared are amongst the most common wireless technologies. The Bluetooth, originally created by Ericsson more than 20 years ago, allows a number of devices to connect to each other wirelessly. It is a high-speed wireless technology used to connect devices such as smartphones, speakers, headsets, laptops, etc.  There are millions of products with incorporated Bluetooth technology available for sale on the market nowadays and it is one of the most commonly-used wireless connection technologies out there.

What is Bluetooth’s Secret?

How does Bluetooth work

But how does Bluetooth work? Over short distances, up to eight Bluetooth devices can pair via this technology, which enables them to exchange data. Every device uses a microchip with an antenna to send and receive signal, and software to process the communication between the hardware. The antenna sends short-range waves that, unlike the infrared wireless technology, do not require an unobstructed space between the receiving and transmitting devices.  One device called a master, can exchange information with up to seven others, called slaves, in a network called piconet. A Bluetooth device can be a member of multiple piconets, and separate piconets can be linked together to form a scatternet. Every device also has a hold mode, which lowers its activity and saves more batter power than in normal mode.

Pros and Cons of Bluetooth

Most of us are not interested in how does Bluetooth work, but what are its advantages. Bluetooth consumes an almost insignificant part of your battery, saving power and allowing you to use your device for a longer period of time. However, low battery consumption limits the technology range to 32 feet or less. Despite the low power drainage, users can transfer information with up to 3 megabits per second with Bluetooth 2.0 standard and up to 24 megabit per second with Bluetooth 3.0. A newer, 4.0 standard has recently been adopted, allowing an even higher transfer speed. It is extremely easy to use – all you have to do is turn it on and pair the devices. When a device is attempting to pair with yours, you have to allow this connection. This makes the technology extremely safe and prevents leakage of sensitive information. In addition, despite the fact that almost every electronic device out there has Bluetooth technology incorporated, there is practically no interference between devices in the same area.
